Using in vim with huge java projects

[alepekhin]

I use vim-lsc plugin and this language server built from sources. It works fine with small and average size Java projects. With huge projects, about several thousands Java files, it also works but uses 500% - 600% of CPU for a long time that I don't like. It turns on the fan on my computer. How can I make it works slowly? Currently I have to switch off LSP support at all for that projects
